Warren Buffett and Bill Gates were able to line up more than $100 billion in charity pledges from the American elite, but many of the richest in the U.S. haven't take the pledge to donate a majority of their assets to charity. Click here to see the billionaries who are also rich in the giving spirit.
NET WORTH: $5.5 billion eBay founder Pierre Omidyar is one of three technology sector executives on the Buffett/Gates list. Like many of the big-name donors, even before Buffett and Gates began their soft sell, Omidyar had committed $900 million of his $5.5 billion fortune to charity. Omidyar was not the only eBay fortune to make the pledge to charity. Jeffrey Skoll, the founder and first president of eBay ( EBAY), was also among the 40 donors on the list, and notably, is the only Canadian among the group. Buffett and Gates have targeted the Chinese billionaire set first among international donor candidates, and are now trying to put the Chinese billionaire set at ease in regards to their charity world tour. The two U.S. billionaires wrote a letter in response to questions from China's state news agency Xinhua, stressing the fact that while "Some people have wondered if we're coming to China to pressure people to give. Not at all." Not that the shrewd Gates and Buffet did not put on the onus on China's billionaires to step up and take their place among the philanthropic leaders of the world, in the same way that China is quickly becoming a leader in every other global rankings. "The present generation of successful entrepreneurs has an opportunity to set an example for future generations in China.... It is very likely they will have a substantial impact on how large-scale philanthropy grows and develops in modern China," the Buffett/Gates letter to the Chinese news agency Xinhua stated, according to a recap on Reuters. Buffett and Gates aren't just headed to China, but also plan a trip to India to soft sell charitable giving on the emerging global elite, though they've stopped short of speaking in terms of plans for a dedicated global campaign. The Forbes list of the World's Richest has increasingly featured the capitalist titans of the emerging markets. Among old school titans of U.S. capitalism that are featured on the Buffet/Gates list of billionaires agreeing to give away a majority of their wealth -- though not in the Top 10 -- are energy fund manager and former corporate raider T. Boone Pickens, IAC/Interactive Corp. ( IACI) CEO Barry Diller, global power company AES ( AES) co-founder Roger Sant, Domino's Pizza founder Thomas Monaghan, and Ted Turner.
